1 SAFETY DATA SHEET Refrigerant Gas R422D 1. Product and Company Identification Product Name: Distributor: Refrigerant Gas R422D National Refrigerants Ltd 4 Watling Close Sketchley Meadows Business Park Hinckley Leicestershire LE10 3EZ Tel: +44(0) Fax: +44(0) [email protected] Emergency Telephone Numbers: IN AN EMERGENCY DIAL 999 (UK Only) For specialist advice in an emergency telephone (+44) (0) Hazard Identification Colourless, volatile liquid with ethereal and faint sweet odour. Non-flammable material. Overexposure may cause dizziness and loss of concentration. At higher levels CNS depression and cardiac arrhythmia may result from exposure. Vapour displaces air and can cause asphyxiation in confined spaces. At higher temperatures (>250 o C) decomposition products may include Hydrofluoric Acid (HF) and carbonyl halides. Potential Health Hazard Skin: Irritation would result from a defatting action on tissue. Liquid contact could cause frostbite. Eyes: Liquid contact can cause sever irritation and frostbite. Inhalation: When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur. At high levels cardiac arrhythmia may occur. 3. Composition/Information on Ingredients R422D Page 1 of 6

2 Chemical Nature: Blend of halogenated alkanes Component EC-No. CAS No. Weight % 1,1,1,2-Tetrafluoroethane (HFC134a) Pentafluoroethane (HFC125) Isobutane First Aid Measures Skin: Promptly flush with water for at least 15 minutes. If there is evidence of frostbite, bathe (do not rub) with lukewarm (not hot) water. If water is not available, cover with a clean, soft cloth or similar covering. Get medical attention if symptoms persist. Eyes: Immediately flush eyes with large amounts of water for at least 15 minutes (in case of frostbite water should be lukewarm, not hot) lifting eyelids occasionally to facilitate irrigation. Get medical attention. Inhalation: Immediately remove to fresh air. If breathing has stopped, give artificial respiration. Use oxygen as required, provided a qualified operator is available. Get medical attention. Do not give epinephrine (adrenaline). Ingestion: Hospitalise. Ingestion is unlikely because of the physical properties of the material. Advice to Physician: Because of the possible disturbance of cardiac rhythm, catecholamine drugs, such as epinephrine, should be used with special caution and only in situations of emergency life support. Treatment of overexposure should be directed at the control of symptoms and the clinical conditions. 5. Fire Fighting Measures Extinguishing Media: All extinguishing agents are suitable. Use any standard agent chose the most appropriate for type of surrounding fire (the material itself is not flammable). Specific Hazard: Pressurised container. On heating there is a risk of bursting due to internal pressure build-up. At high temperatures thermal decomposition gives toxic vapours Hydrofluoric Acid (HF) and carbon oxides. Specific fire fighting methods: Stay upwind. Evacuate the personnel away from the fumes. Cool down the containers/equipment exposed to heat with water spray. Protection of the fire fighters: Wear a self-contained breathing apparatus and a protective suit. 6. Accidental Release Measures Personal Precautions: Avoid contact with skin and eyes. Do not breathe the gas. No naked flames. DO NOT smoke. In enclosed areas wear self contained breathing apparatus. (see Section 8, Exposure controls/ personal protection). Vapour is heavier than air. Shut off low-level openings in the vicinity (ventilation shafts, drains etc.). Prevent the product from entering cellars, basements since the vapour may create a suffocating atmosphere. Stop the leak. Ventilate the spillage area. Ventilate enclosed areas, basements, pits etc. 7. Handling and Storage Refrigerant Gas R422D Page 2 of 6

3 Handling: Avoid breathing the vapour. Avoid liquid contact with the eyes, skin or clothing. Do not puncture or drop the cylinders. Do not expose them to open flame or excessive heat. Follow standard precautions for handling and use of compressed gas cylinders. Storage: Store in a cool, well-ventilated area of low fire risk and out of sunlight. Protect cylinders and fittings from physical damage. Storage in subsurface locations should be avoided. Close valve tightly after use and when empty. Technical Measures: The vapour is heavier that air. Storage area should be equipped with low-level ventilation. High concentrations may be produced at low levels where general ventilation is poor. In such cases provide adequate ventilation or wear suitable respiratory equipment with positive air supply. For correct refrigerant composition system should be charged using the liquid phase not vapour phase. Liquid refrigerant transfers between containers and to and from system can result in static charge generation. Ensure adequate earthing. Packaging Material: Recommended: Steel To be Avoided: Alloys containing more that 2% magnesium. Plastic materials. 8. Exposure Controls & Personal Protection Engineering Control: Provide local ventilation at filling zones and areas where leakage is probable. Mechanical (general) ventilation may be adequate for other operating and storage areas. Personal Protective Equipment Skin Protection: Skin contact with refrigerant may cause frostbite. General work clothing and gloves (leather) should provide adequate protection. If prolonged contact with the liquid or gas is anticipated, insulated gloves constructed of PVA, neoprene or butyl rubber should be used. Any contaminated clothing should be promptly removed and washed before reuse. Eye Protection: For normal conditions wear safety glasses. Where there is a reasonable probability of liquid contact wear chemical safety goggles. Respiratory Protection: None generally required for adequately ventilated work situations. For accidental release or non-ventilated situations, or release in confined space, where the concentration is above 1000 ppm use self contained approved breathing apparatus or suitable respirator. Hygiene measures: Do not smoke when charging or reclaiming refrigerant. Avoid contact with skin and eyes. Avoid inhaling the vapour. Occupational Exposure Limits: Component TWA 1,1,1,2-Tetrafluoroethane 1000 ppm (4240 mg/m 3 ) Pentafluoroethane 1000 ppm (4900 mg/m 3 ) Isobutane 1000 ppm Physical and Chemical Properties Appearance: Physical State: Clear, colourless liquid and vapour. Gas at ambient pressure and temperature. Refrigerant Gas R422D Page 3 of 6

4 Chemical Formula: 1, 1, 1, 2-Tetrafluoroethane CF 3 -CH 2 F Pentafluoroethane CF 3 -CHF 2 Isobutane CH 3 -CH-(CH 3 ) 2 Odour: Faint ethereal odour. Density: 1.15 kg/l at 25 o C ph Not Applicable Boiling Point/Range: -43 o C at atmospheric pressure Vapour Pressure: 164 psia at 25 o C Vapour Density: 3.9 at 25 o C (Air = 1) Solubility in Water: <0.5% wt at 25 o C 9. Stability and Reactivity Stability: Stable at ambient temperature and under normal conditions of use. Conditions to avoid: Keep away from heat and sources of ignition. Avoid contact with flames and red hot metallic surfaces. Hazardous decomposition products: On contact with very hot surfaces, or flames, thermal decomposition (Pyrolysis) releases toxic gasses (hydrofluoric acid and possibly carbonyl halides). 10.
